[0002] my country is located at the junction of two major geological tectonic plates, where earthquakes occur frequently, causing great harm and heavy losses. At present, my country's earthquake fortification design aims to minimize casualties caused by earthquakes, and less consideration is given to the earthquake safety of important items in buildings and immovable cultural heritage. Cultural relics or precision instruments and equipment are severely damaged in earthquakes, and the safety of high-value items such as cultural heritage, cultural relics collections, and precision instruments is of great significance.

[0003] At present, mature and reliable seismic isolation devices have been developed for the earthquake / vibration protection of high-value items such as cultural heritage, cultural relics, and precision instruments. When designing a seismic isolation device, it is necessary to reserve sufficient movable gaps with the surrounding foundation ground to ensure that it can deform freely under the action of an earthquake. The commonly used construction method is to set up a seismic isolation trench. The top cover of the seismic isolation trench needs to meet the bearing function of daily walking and covering maintenance, and it needs to have a certain horizontal displacement activity to ensure the free deformation of the seismic isolation device, and it needs to prevent it from falling into the seismic isolation trench and affecting the function of the seismic isolation device.

The movable linear bearing and the vertical supporting mechanism can slide between the fixed linear bearing A and the fixed linear bearing B along the optical axis; the optical axis can slide in the fixed linear bearing A; The upper folding cover plate is divided into two independent parts along the length direction of the seismic isolation groove, and the two upper folding cover plates are jointly supported on the top of the vertical support mechanism and are hinged to the vertical support mechanism through a pin shaft; An oblique folding mechanism is connected between the upper folding cover plate near the fixed linear bearing B and the fixed linear bearing B.

An oblique folding mechanism is connected between the upper folding cover plate near the movable linear bearing and the movable linear bearing. One end of the oblique folding mechanism is hinged to the upper folding cover plate through a pin, and the other end is hinged to the movable linear bearing through a pin.

[0007] The present invention provides a connecting rod folding type seismic isolation trench cover device. Further, when the two upper folding cover plates are in a flat state, the vertical support mechanism, the oblique folding mechanism and the optical axis form a stable triangular structure.

[0021] like Figure 1-Figure 3 As shown, the present invention discloses a connecting rod folding type seismic isolation trench cover device, including a seismic isolation trench, a seismic isolation device 1 located on both sides of the seismic isolation trench, a structural steel beam 2 installed on the top of the seismic isolation device 1, an upper folding cover plate 9 and at least two groups of support components. The present application takes two groups of support components as an example for explanation.

[0022] Each group of supporting components includes a fixed linear bearing A3, a fixed linear bearing B4, an optical axis 5, a movable linear bearing 6, an oblique folding mechanism 7 and a vertical supporting mechanism 8. The fixed linear bearing A3, the fixed linear bearing B4, the optical axis 5 and the movable linear bearing 6 are located in the same horizontal plane to ensure that the horizontal deformation of the seismic isolation device 1 triggered by the earthquake force can enable the connecting rod folding type seismic isolation trench cover device to move in the direction of the optical axis 5. The optical axis 5 passes through the fixed linear bearing A3, the movable linear bearing 6, the vertical supporting mechanism 8 and the center hole set on the fixed linear bearing B4 in sequence, and one end of the optical axis 5 is fixedly connected to the fixed linear bearing B4, the movable linear bearing 6 and the vertical supporting mechanism 8 can slide between the fixed linear bearing A3 and the fixed linear bearing B4 along the optical axis 5; the optical axis 5 can slide in the fixed linear bearing A3; the fixed linear bearing A3 is fixedly connected to the structural steel beam 2, and the fixed linear bearing B4 is placed on the structural steel beam 2. The present application can realize the bearing and covering functions of the seismic isolation trench cover under normal conditions, provide the same-direction displacement space required by the seismic isolation device 1 in two directions under the triggering of earthquake force, and ensure that the seismic isolation trench cover is on the connecting rod optical axis 5 and does not fall into the seismic isolation trench to affect the normal operation of the seismic isolation device 1.

[0023] The upper folding cover plate 9 is divided into two independent parts along the length direction of the seismic isolation groove. The two upper folding cover plates 9 are jointly supported on the top of the vertical support mechanism 8 and are hinged to the vertical support mechanism 8 through a pin shaft, thereby playing a role in vertically supporting and connecting the upper folding cover plates 9.

[0024] An oblique folding mechanism 7 is connected between the upper folding cover plate 9 near the fixed linear bearing B4 and the fixed linear bearing B4. One end of the oblique folding mechanism 7 is hinged to the upper folding cover plate 9 through a pin shaft to ensure that when the optical axis 5 moves horizontally, the two parts of the upper folding cover plate 9 can be turned inward, contracted and folded by the thrust of the oblique folding mechanism 7, thereby ensuring that the horizontal deformation of the seismic isolation device 1 triggered by the earthquake force is not affected by the seismic isolation groove and its cover plate; the other end is hinged to the fixed linear bearing B4 through a pin shaft to ensure that when the optical axis 5 moves horizontally, the oblique folding mechanism 7 and the fixed linear bearing B4 and the movable linear bearing 6 only have relative rotation but no relative displacement.

[0025] An oblique folding mechanism 7 is connected between the upper folding cover plate 9 near the movable linear bearing 6 and the movable linear bearing 6. One end of the oblique folding mechanism 7 is hinged to the upper folding cover plate 9 through a pin, and the other end is hinged to the movable linear bearing 6 through a pin, thereby.

[0026] When the two upper folding cover plates 9 are in a flat state, the vertical support mechanism 8, the oblique folding mechanism 7 and the optical axis 5 form a stable triangular structure, thereby ensuring the support and bearing effects of the support assembly.

[0027] The two sets of movable linear bearings 6 are connected by steel plates to ensure that the movable linear bearings 6 move simultaneously and drive the oblique folding mechanism 7 and the upper folding cover plate 9 to fold and deform inwards.

[0028] The two groups of fixed linear bearings B4 are connected by steel plates to ensure that the two groups of fixed linear bearings B4 and the optical axis 5 move simultaneously, and drive the oblique folding mechanism 7 and the upper folding cover plate 9 to fold and deform inwards.

[0029] When the upper folding cover plate 9 is laid flat, the oblique folding mechanism 7 forms an angle of 45° with the optical axis 5, ensuring that the connecting rod folding seismic isolation trench cover plate has good load-bearing and supporting performance.

[0030] A steel rib is provided at the lower part of the upper folding cover plate 9 to ensure that the load-bearing deformation of the upper folding cover plate 9 is less than 2 mm.

[0031] The oblique folding mechanism 7 comprises an oblique support rod, one end of which is connected to the upper folding cover plate 9 via a pin, and the other end of which is connected to a fixed linear bearing B4 or a movable linear bearing 6 at a corresponding position via a pin.

[0032] The vertical support mechanism 8 includes a support rod, a center hole is opened at the lower end of the support rod, and the upper end is supported on the bottom surfaces of the two upper folding cover plates 9 and is hinged with the upper folding cover plates 9 through a pin; the upper folding cover plates 9 are opened at the position of the support rod for the support rod to pass through; the upper end of the support rod extends to the side away from the two upper folding cover plates 9 to extend the notch range and is supported on the bottom surface of the upper folding cover plates 9.

[0033] When the left seismic isolation device 1 displaces to the right and contacts the fixed linear bearing B4 to generate a rightward thrust, the fixed linear bearing B4 drives the left oblique folding mechanism 7 to rotate counterclockwise through the pin shaft, thereby driving the top pin shaft of the oblique folding mechanism 7 to rotate, so that the upper folding plate folds inward to complete the required displacement space.

[0034] When the right seismic isolation device 1 displaces to the left, it contacts the fixed linear bearing A3 and generates a thrust to the right. The fixed linear bearing A3 drives the right oblique folding mechanism 7 to rotate clockwise through the pin shaft, thereby driving the top pin shaft of the oblique folding mechanism 7 to rotate, causing the upper folding plate to fold inwards and complete the required displacement space.

[0035] like Figure 2 As shown, the seismic isolation devices 1 on the left and right sides can simultaneously generate displacement to the left or right.

[0036] Here’s how to do it: The fixed linear bearing A3 is screwed and connected to the upper structural steel beam 2 of the seismic isolation device 1, serving as a force-bearing support structure for the connecting rod folding cover plate.

[0037] The displacement of the right-side seismic isolation device 1 triggered by the seismic force contacts the movable linear bearing 6, pushing the two sets of oblique folding mechanisms 7 and the vertical support mechanism 8 on the right side to move synchronously along the direction of the optical axis 5. The relative displacement between the right-side oblique folding mechanism 7 and the vertical support mechanism 8 gradually decreases, and drives the upper folding plate mechanism to rotate upward without separating from the optical axis 5, thereby realizing the displacement space required by the right-side seismic isolation device 1 under the action of the seismic force.

[0038] The displacement of the left seismic isolation device 1 triggered by the earthquake force contacts the fixed linear bearing B4, pushing the two groups of oblique folding mechanisms 7 and the vertical support mechanism 8 on the left side to move along the right direction together with the optical axis 5. The relative displacement of the left oblique folding mechanism 7 and the vertical support mechanism 8 gradually decreases, and drives the upper folding plate mechanism to rotate upward without separating from the optical axis 5, thereby realizing the displacement space required by the left seismic isolation device 1 under the action of the earthquake force.

[0039] After the upper folding plates are pushed open by an earthquake or other external forces, the upper folding plates can be pressed down manually to restore the two upper folding plates to a horizontal plane, thus completing the initial working state of the connecting rod folding seismic isolation trench cover.

[0040] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
